Goatfaking is when you’re faking being the GOAT (greatest of all time). Generally used to humble those with large egos when they claim to be the GOAT when they are, in fact, just goatfaking.
Person One: Bro I’m boutta destroy you in a 1v1 bro

Hym "I'm still going to need that wife of yours... Here's the plan: You hammer the retard she's with to death. I will then take her... And lock her up... In a crudely constructed cabin in the woods (I don't know how to build cabins)... End of plan. We can do it Goatee... We can do it today."
